“…Moreover, the 2D carbon nanosheets could efficaciously ensure sufficient electrocatalytic activity and robust durability of transition metal compounds due to the alleviation of metal species aggregation during high-temperature pyrolysis. 82,257 Thus, it is necessary to decorate metal atoms or species on N-doped 2D carbon nanosheets to enhance their electrochemical activity. For example, Ren et al uniformly anchored N-coordinated metal species such as Fe–N, Co–N, Ni–N, Cu–N, Mn–N, Mo–N and Sn–N in 2D carbon nanosheets (M–N–C PCSs) to reduce energy barriers and accelerate ORR and OER kinetics.…”

“…In electrochemical testing, Cr-Co-NS@CNFs exhibited a higher ultimate diffusion current density ( J l ) and ORR activity, attributed to the hierarchical structure accelerating the electron transfer process and inhibiting the aggregation of Cr and Co active centers. 50 The development of hierarchical structures provides a simple strategy for the preparation of bifunctional catalysts: by assembling structures with active sites for ORR and OER, both reactions can proceed without mutual interference. Yoon et al utilized the in situ growth method to obtain CoO@CoN nanorods anchored on nitrogen-doped CNFs (CoO@CoN/NCNFs), which exhibited a higher E 1/2 , J l for the ORR and a lower overpotential (E j ) for the OER.…”

“…However, in the current literature, the vast majority of reported works continue to use excessive amounts of zinc as anodes to demonstrate the rechargeability of the zinc-air battery configuration studied. [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41] In this context, it was already mentioned in the 1990s during the development of mechanically rechargeable zinc-air batteries that this situation imposed by improper balancing should "not become an additional anchor the car or truck has to haul" besides the inevitably necessary. Consequently, this implies that metallic zinc present must be used completely for the electrochemical conversion.…”

advance at the end of the 1990s, the current electrification needs in nearly all sectors would be difficult to imagine, striving our daily life from miniaturized applications up to massive energy storage demands in transportation. With regards to zero-emission passenger transportation using battery powered vehicles, the advantage of the lithium-ion battery seems currently undisputed.This steadily increasing demand for lithium-ion batteries currently raises the question of whether and how long the availability of raw materials can be guaranteed. Moreover, the constantly expanding range of applications for the lithium-ion technology means that the safety aspects to be fulfilled are becoming ever more stringent, which are known to be the weak spot of this system due to the high reactivity of lithium. [1][2][3][4] Consequently, the lithium-ion battery is subjected to enormous performance pressure, because as a universal remedy it must meet the most diverse requirements. [5] Nevertheless, the lithium-ion battery is meanwhile used ubiquitously due to the current absence of suitable and technologically mature alternatives, which further exacerbates the raw material situation. [5,6] Due to the enormous application potential of the lithium-ion battery, other battery technologies (nickel-cadmium, nickelmetal hydride, lead-acid) that have been known for a long time are meanwhile pushed out of the market or represent only niche products known for just a specific application. [7][8][9] This is true for the zinc-air battery too, which is mainly known to the consumer as a non-rechargeable battery for hearing aids. However, it has also been known as a battery and mobile charger for military applications, since it is heavy duty under the most adverse conditions, while allowing high energy density and maintaining high safety requirements. [10][11][12] Yet, already in the mid-1990s, zinc-air batteries were on the verge of their breakthrough as a rechargeable energy storage device that would usher in the complete electrification of Germany's postal fleet at that time. [13] As a mechanically rechargeable battery system in a van fleet of 60 cars, the used zinc metal (Zn) anodes were removed as a full pack from the spent battery set and replaced by a fresh metal pack to recover the battery. With that, a usage of more than 320 km with an energy density of 200 Wh kg −1 had already been achieved under realistic conditions. [13] In times of an ever-increasing demand for portable energy storage systems, post-lithium-based battery systems are increasingly coming into the focus of current research. In this realm, zinc-air batteries can be considered a very promising candidate to expand the existing portfolio of lithium-based rechargeable battery systems due to their high theoretical energy density of 1086 Wh kg −1 . Despite a steady increase in research over the past 5 years, a breakthrough in realizing fully electrically rechargeable zinc-air batteries has yet to come. This perspective article highlights pitfalls that have probably hampered ...
